chore(renovate): enable the pre-commit manager, pin validator at v1.36.0

The pre-commit config header promises that Renovate bumps the pinned
hook revs automatically; the pre-commit manager is opt-in and was never
enabled, so the pin stayed where scaffolding left it while CI validates
against skill-repo-skill main. Enables the manager and pins the
validator hooks at v1.36.0, matching what CI enforces today.

Part of netresearch/skill-repo-skill#252.
